`__msvc_bit_utils.hpp` was added in a recent version of MSVC, and it is causing build errors for SwiftCompilerSources:
```
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\include\numeric:598:12: error: function '_Select_countr_zero_impl<unsigned long long, (lambda at C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\include\numeric:598:55)>' with deduced return type cannot be used before it is defined
return _Select_countr_zero_impl<_Common_unsigned>([=](auto _Countr_zero_impl) {
```
This change references the `__msvc_bit_utils.hpp` header from the modulemap. Since we still need to support older versions of Visual Studio that do not provide `__msvc_bit_utils.hpp`, this also teaches ClangImporter to inject an empty header file named `__msvc_bit_utils.hpp` into the system include directory, unless it already exists.
